Different causes. Barrel-wear, from jacketed rounds, actually wears the rifling at a faster rate(than cast); leading, from build-up of cast bullets may be a PITA, but is removable.sluggo":29q6t816 said:How many jacketed bullets do you put down the tube before accuracy starts to suffer? Same question for cast bullets.
Gotcha. You should not see any accuracy changes with jacketed rounds at all. Cast would depend on quantity and hardness. I would suspect you would see some variance after a box or so with un-alloyed slugs, but with mass produced or well made home-pours I would expect more change due to a sore hand.sluggo":1vh8o492 said:This was more of a how many rounds do you fire between cleanings. With my rifles I usually figure about 15 rounds and it's time to clean because accuracy is declining. That's what I'm wondering.
